Forked from https://gist.github.com/eric1234/5628416

Adjustments:

• No environment based .env filenames
• No need for APP_ENV

Purpose

Somewhat like dotenv but for PHP.

The goals is to remove all config scattered about in files and have one authoritative source for that config info. Searches for .env up the directory tree until it gets to DOCUMENT_ROOT.

Usage

Create a .env file in the root of your website. In that file put all configuration. Example:

DB_DSN=mysql:dbname=mydb;host=myhost
DB_USERNAME=myuser
DB_PASSWORD=mypass

Then in your code you can simply access these values via the $_ENV global.

env.php

<?php

namespace Env;

$env = ".env";
$cur = realpath(__DIR__);
$root = realpath($_SERVER['DOCUMENT_ROOT']);
$found = false;

while( !$found && strpos($cur, $root) == 0 ) {
  $file = null;
  if( file_exists("$cur/$env") ) $file = "$cur/$env";
  if( file_exists("$cur/environments/$env") ) $file = "$cur/environments/$env";
  if( $file ) {
    foreach(explode("\n", file_get_contents($file)) as $line) {
      if( empty($line) ) continue;
      list($var, $val) = explode("=", $line, 2);
      $_ENV[$var] = $val;
    }
    $found = true;
  }
  $cur = dirname($cur);
}
